A New Perspective on Single-Brood Mosquito Control: Mosquito control presents a complex challenge for public health professionals. With budgets already stretched to the limit, districts are looking for a solution that can deliver more than just effective control. They need a flexible solution that can deliver real operational benefits that make a bottom-line difference for budgets and resources.

15. WHAT IS VECTOPRIME? 15
1. VectoPrime FG is a BioFuse™ based, combination AI
granule for single brood mosquito control…
2. …offering the industry’s widest application window for
single brood control (all instars + prehatch)…
3. …and provides end-user savings with low rates and
operational flexibility from the global leaders in larviciding
technology.
27. FIELD EFFICACY: PRE-FLOOD APPLICATIONS
• Efficacy was measured against immature floodwater mosquitoes
including:
– Aedes taeniorhynchus
– Aedes vexans
– Aedes dorsalis
• Rates ranged from 10 to 20 pounds per acre
• Pre-flood treatment intervals of 2, 3, 4 and 7 days were evaluated

28. FIELD EFFICACY: PRE-FLOOD APPLICATIONS 28
Percent reduction of Aedes spp., in pre-flood studies following treatment with VectoPrime FG at various rates
29. FIELD EFFICACY: POST-FLOOD APPLICATIONS
• Efficacy was measured against immature floodwater mosquitoes
(Aedes taeniorhynchus, Aedes vexans, and Aedes dorsalis) at rates
ranging from 1.25 to 5 pounds per acre
• Efficacy against immature Culex pipiens and Culex tarsalis was also
demonstrated at rates from 2.5 to 10 pounds per acre
• Impact of water depth was evaluated in a study with Culex
quinquefasciatus

As each of these active ingredients delivers optimal activity against different mosquito larval stages, multiple products are often used to manage changing scenarios.
In addition, many mosquito control programs manage multiple floodwater sites, but they have limited capacity to survey and treat all the sites once they are flooded. By the time many programs can reach a site, the larvae may have already progressed into late instars, and in some cases a mix of young and late instars.
As a result, some programs have moved to pre-hatch products that have the residual capacity to treat multiple floods. However, in many cases, residual control of multiple floods is not needed.
Valent BioSciences’ experience in developing value-added products with combinations of active ingredients via its proprietary BioFuse™ technology has allowed for the development of the industry’s most flexible mosquito larval control solution for single brood mosquitoes: VectoPrime®.
VectoPrime offers abatement professionals superior operational flexibility with a wider application window. The ability to apply VectoPrime prior to flooding means you can plan ahead instead of having to react to changing environmental conditions, saving time and freeing up resources that would have been required for additional field surveillance and additional treatments. In addition, working with a single solution that kills all larval instars also allows you to streamline inventories and simplify replenishment.
In other words, you can start and end your week with the same solution.
By combining Bti and (S)-methoprene into individual micro particles, VectoPrime® delivers effective control for multiple target mosquito species throughout all four instars. BioFuse™ technology ensures that each micro particle contains both AIs and they are delivered in appropriate ratios for consistent application and results.
With its revolutionary double “plus” potency formulation and higher bulk density, VectoPrime® can cut application rates directly into water in half compared to current single-brood products, delivering more value per acre than conventional single-brood options. By doubling the effectiveness of every payload, you can save on fuel, maintenance, and labor costs.
The industry-standard granule size (same size as VectoBac® GS, VectoLex® FG and VectoMax® FG) streamlines calibration and characterization of application equipment. And the unique combination of AIs means you need only perform calibration and characterization once for your single-brood habitats. In addition, VectoPrime® granules are non-abrasive, reducing attrition to application equipment when compared to sand-based products.
Currently, single-brood Bacillus thuringiensis subsp. israelensis (Bti) products are used primarily against early to mid instar larvae, and (S)-methoprene (and other chemical / biochemical active ingredients) single-brood products are used primarily against mid to late instar larvae. In either case, the type of single-brood product to be used can be determined only after the habitat has been sampled.
